Remo Astro Flower – Bloom Booster for Indoor Growing

Remo Astro Flower – High-Density Bloom Stimulator

Developed by Canadian brand REMO, Astro Flower is a bloom stimulator formulated for demanding growers who want dense, heavy, and aromatic flowers. Designed to integrate into any nutrition program, it boosts the bloom phase regardless of light source — full spectrum LED, HPS, or other. Available in 1 L, 5 L, 10 L, and 20 L.

Benefits for your crop

Astro Flower acts directly on flower structure to increase yield and inflorescence quality during the bloom phase.

• Flower densification — Promotes the formation of compact and well-defined calyces, visibly increasing head density at the end of the flowering cycle.
• Increase in dry weight — Bloom cofactors stimulate the accumulation of dry matter for optimized final yield.
• Improvement of aromas and terpenes — The formulation supports the biosynthesis of aromatic compounds, strengthening the terpene profile of harvested flowers.
• Universal compatibility — Usable in soil, coco, hydroponics, or aeroponics, Astro Flower adapts to all substrates and irrigation systems.

Technology and performance

Remo Astro Flower is based on a formulation of amino acids and biological extracts that target the physiological mechanisms of flowering. The supply of bioavailable phosphorus and potassium supports floral signaling from the first weeks of bloom. Combined with a full spectrum light source with PPFD suited to the flowering phase, it maximizes the potential of every μmol/s delivered by your LED panel or HPS to convert light energy into floral biomass.

Reliability and usage

The REMO range is recognized for the consistency of its formulations, batch after batch. Astro Flower is dosed and concentrated to integrate seamlessly into an existing nutrition program, with no risk of major imbalance if recommended dosages are followed. Its concentration allows cost-effective use regardless of the chosen size, from the 1 L format for small setups to the 20 L format for regular production growers.

How to use Remo Astro Flower?

Integrate Astro Flower from the start of the bloom phase for maximum effect throughout flowering.

• Start in week 1-2 of bloom — Introduce Astro Flower at the transition to 12/12 (or at floral initiation) to support the veg/bloom transition and prepare floral structure.
• Progressive dosing — Follow the REMO dosing chart and gradually increase the dose based on plant response, monitoring solution EC and pH.
• Combine with end-of-cycle booster — Pair Astro Flower with a ripener or flushing agent at the end of bloom to maximize resin accumulation and facilitate maturation.
• Adapt to your lighting — Under high PPFD LED (800–1200 μmol/m²/s during bloom), slightly increase nutrient inputs to match increased photosynthetic rate.

Regular and measured use of Astro Flower throughout bloom ensures uniform flowering and reproducible yield cycle after cycle.

Joseph's tip: "I've been using Astro Flower for several cycles under our full spectrum LED panels, and what I observe is a clear improvement in flower compactness from week 3 of bloom onward. My advice: don't overlook PPFD — a bloom stimulator can only express its full potential with sufficient photonic flux density, at least 900 μmol/m²/s at peak flowering."
